I enjoyed the irony of the fact that the same album contains an interview with a rock star who has just released an album of his own on which he has neither written nor performed the songs - The film Spinal Tap borrowed heavily from this Sellers parody in my opinion.

The Trumpet Volunteer is indeed a classic sketch too. The main character is a pop star "Fred Iron" (no prizes for guessing who he was taking the p*** out of!) who has recorded a pop version of the "Trumpet Voluntary". The rather staid 1950s BBC-type interviewer says (all from memory so may not be 100% right):

I suppose you know the Trumpet Voluntary has been attributed to Jeremiah Clarke?

Fred: Er... no I di'n't know that, as it 'appens.... er... what d'yer mean, "attributed"?

Interviewer: Well, some people think he may have written it.

Fred: Oh, that! Well, I'm not gonna say wevva 'e wrote it or 'e didn't. My only concern is it's aht o' copyright!

:-)

I thought the song was a brilliant spoof too.
